WULF TERAWULF INC. Insider Trading

CEO Paul B. Prager sold 137,500 shares of WULF at $26.60; current price $23.58, stock down 21.0% from 52-week high. Pre-arranged 10b5-1 plan.

Paul B. Prager, Chief Executive Officer, sold 137,500 shares at $26.60 on 2026-06-29 as part of a pre-arranged 10b5-1 trading plan, reducing his holdings from 4,082,552 to 3,945,052 shares. The stock currently trades at $23.58, down 21.0% from its 52-week high of $29.84. His prior trades at WULF show mixed outcomes: recent sales from late April through May achieved 30-day returns ranging from −2.8% to +28.0%, though none yet have measurable 90-day results. Because this transaction is scheduled under a 10b5-1 plan rather than discretionary, it does not reflect current market judgment; however, the company's unprofitable recent full year and −427.6M net income warrant investor attention to fundamentals beyond trading activity.

CEO Paul B. Prager sells 333,300 shares (333.3K) for $8,389,968.83 via 10b5-1 plan; holds 4,082,552 shares post-transaction.

Paul B. Prager, Chief Executive Officer of TERAWULF INC., executed 3 separate sales totaling 333,300 shares for $8,389,968.83 across May 26–27, 2026, at prices ranging from $24.43 to $26.57 (blended average $25.17). This transaction is part of a pre-arranged 10b5-1 trading plan and therefore represents scheduled, not discretionary, activity. Prager retains 4,082,552 shares post-transaction, representing a 7.5% reduction from his prior 4,415,852-share position. Against company fundamentals showing $34.0M in latest quarterly revenue but a negative full-year net income of $-427.6M, this scheduled divestiture warrants investor attention to whether the plan timing (established earlier, now executing) reflects conditions known at its adoption versus current market trajectory.

WULF CEO Prager sells 216,700 shares across 4 transactions for $4,492,945.10 (blended avg $20.73), reducing holdings by 19.7%

Paul B. Prager, Chief Executive Officer of TeraWulf Inc., executed 4 separate sales totaling 216,700 shares for $4,492,945.10 on April 27–28, 2026, at prices ranging from $20.51 to $21.29, reducing his holdings from 1,101,020 to 884,320 shares (-19.7%). The company reported revenue of $50,578,000.00 in its latest quarter with annual revenue growth of +20.3%, but remains unprofitable with a net income of $-455,050,000.00 in its most recent full fiscal year. His prior three sales at WULF (on March 24–25, 2026) all showed positive 30-day outcomes (+26.6%, +13.6%, +18.1%), suggesting he does not have a pattern of selling ahead of declines at this ticker. The current stock price of $20.80 is -2.9% from the 52-week high of $21.43 and has risen +39.7% over 30 days and +37.7% over 90 days, placing this sale at an elevated price level relative to recent history. Given the company's ongoing losses despite revenue growth and the substantial size of the sale, monitoring whether this signals any shift in management's near-term outlook warrants attention from investors holding WULF.

WULF CEO Prager sells 275,000 shares (−55.9% of holdings) for $4.5M via scheduled 10b5-1 plan

Paul B. Prager, CEO of TERAWULF INC., executed 3 separate sales totaling 275,000 shares for $4,544,999.28 across two days (March 24–25, 2026), at prices ranging from $16.10 to $17.62 with a blended average of $16.53. This sale reduced his holdings from 491,700 shares to 216,700 shares, a -55.9% reduction in his position. The transaction was conducted as part of a pre-arranged 10b5-1 trading plan, meaning the sales were scheduled and not discretionary trading decisions. The magnitude of the reduction—eliminating more than half his stake—represents a significant change in the CEO's ownership exposure to the company, though investors should note the pre-planned nature of the execution limits inferences about his real-time conviction.

Director Bucella purchased 1,665 shares of WULF at $15.04; 5th buy in 7 days amid $-455.0M net loss, 90-day return +20.6%

Bucella executed his fifth purchase of TERAWULF shares in seven consecutive calendar days (2026-03-09 through 2026-03-20), accumulating 1,665 shares on this date for $25,041.60, increasing his holdings to 280,052 shares (+0.6%). The buying pattern is notable: five discretionary open-market purchases within a compressed timeframe suggest sustained interest at depressed prices. Context adds complexity: the company reported net income of $-455.0M in its most recent period despite revenue of $50,578,000 and 20.3% year-over-year revenue growth, indicating significant unprofitability. Current price stands at $15.10, only 0.4% above the transaction price but -15.7% from the 52-week high; over 90 days, WULF has gained +20.6%, and over 30 days it has declined -1.8%. Bucella's cross-ticker insider track record shows 10 prior buys with an average 90-day return of +2.7% and a 50% win rate, but his same-ticker trades at WULF are too recent to evaluate. The rapid sequence of purchases into negative profitability warrants close attention to corporate strategy and cash burn rates.

Director Bucella purchased 4,835 shares at blended avg $15.57 in 3 separate buys over 3 days (Mar 17-19); holdings now 278,387 shares. Stock +25.7% (90d) but unprofitable firm.

Bucella, as a Director, executed three separate open-market purchases totaling 4,835 shares for $75,291.19 between 2026-03-17 and 2026-03-19 at prices ranging from $14.96 to $16.00—all near current price of $15.74. Over his cross-ticker track record, his 7 prior open-market buys averaged +4.3% return over 30 days and +2.7% over 90 days with a 50.00% win rate. At WULF specifically, he has accumulated 5 prior buys since 2026-03-04, all within the last two weeks and none yet measurable for outcome. The company is currently unprofitable (net income $-455.0M) despite 90-day stock appreciation of +25.7%, which suggests recent price momentum is driving sentiment rather than fundamental improvement. The rapid accumulation pattern—five trades in thirteen days culminating in this multi-transaction Form 4—coincides with stock momentum but occurs in the context of ongoing losses and a market cap of $6.7B on negative earnings.

CFO Patrick Fleury sold 600,000 shares (entire holding) at $16.14 for $9.7M; now holds zero shares.

Chief Financial Officer Patrick Fleury executed 2 separate sales totaling 600,000 shares for $9,684,000.00 at $16.14 per share, completely liquidating his position. This complete exit is striking given the company's $6.7B market cap and backdrop of 20.3% annual revenue growth ($50.6M latest quarter), but it occurs against a significant headwind: the company reported a net income of $-455.0M over its most recent full fiscal year and remains unprofitable. The CFO's decision to divest his entire shareholding while the stock trades at $15.74 (only 2.7% below where he sold) in a generally strong 90-day uptrend (+25.7%) underscores the disconnect between growth momentum and profitability—a gap that may weigh more heavily on management's view of sustainable value than the recent price appreciation suggests.

Director Bucella buys 1,338 shares (1.3K) of TERAWULF at $14.91 amid 4 prior buys within 6 days

Bucella acquired 1,338 shares at $14.91 on 2026-03-11, extending a buying streak at WULF that includes four additional purchases between 2026-03-04 and 2026-03-09. This clustering of open-market buys within a narrow window—while the stock has declined 8.5% over the past 30 days and sits 18.1% below its 52-week high of $17.92—represents sustained accumulation despite recent price weakness. His cross-ticker track record shows 6 prior buys averaging +4.3% at 30 days, though at WULF specifically, his November 2025 buy returned +33.5% at 90 days while four more recent purchases remain unmeasurable. The company posted $50.6M in quarterly revenue with +20.3% annual growth, but reported a $-455.0M net loss for its most recent full fiscal year, indicating TERAWULF remains unprofitable despite revenue expansion. The pattern of consecutive purchases at a declining stock price warrants investor attention to understand whether this reflects conviction in a temporary dislocation or other motivations.

Director Bucella purchased 2,085 shares across 3 trades totaling $30,071.06 at blended avg $14.42; stock now $13.85, off 22.7% from 52-week high

Bucella Michael C., a director at TeraWulf, executed 3 separate purchases totaling 2,085 shares for $30,071.06 between March 5–9, 2026, at prices ranging from $13.31 to $15.31. His holdings grew modestly to 272,214 shares (+0.8% vs prior). The timing occurs in a weak price environment: the stock trades at $13.85, down 22.7% from its 52-week high and off 3.1% over the past 30 days. At TeraWulf specifically, his prior buy on 2025-11-13 delivered a +33.5% return at the 90-day mark, but his earlier buy on 2025-01-27 resulted in a -28.1% 90-day loss, indicating mixed historical success on this ticker. The company generated $50.6M in quarterly revenue with +20.3% annual growth, but remains unprofitable with a -$455.0M net loss over its most recent full fiscal year.

Director Bucella buys 3.2K WULF shares at $15.78; holdings reach 270.1K (+1.2%). Stock -14.2% from 52w high.

Director Michael C. Bucella purchased 3,171 shares of Terawulf at $15.78, expanding his position to 270,129 shares. The stock has recovered strongly over the past 30 days (+14.4%) but trades -14.2% below its 52-week high of $17.92, near current price of $15.37. Bucella's prior two trades at Terawulf showed mixed timing outcomes: his 2025-11-13 buy was well-timed (90d return +33.5%), while his 2025-01-27 buy underperformed (90d return -28.1%). The company reported revenue of $50,578,000.00 in the latest quarter with annual growth of +20.3%, but remains unprofitable with net income of $-455,050,000.00 over its most recent full fiscal year. This purchase occurs amid near-peak valuations by 52-week measure, following a recent rally.
